### Since XEmacs has configuration requirements that autoconf can't

### We use the m4 quoting characters [ ] (as established by the

###
### Usage: configure config_name
###
### If configure succeeds, it leaves its status in config.status.
### If configure fails after disturbing the status quo,
###     config.status is removed.

### Remove any more than one leading "." element from the path name.
### If we don't remove them, then another "./" will be prepended to
### the file name each time we use config.status, and the program name
### will get larger and larger.  This wouldn't be a problem, except
### that since progname gets recorded in all the Makefiles this script
### produces, move-if-change thinks they're different when they're
### not.
###
### It would be nice if we could put the ./ in a \( \) group and then
### apply the * operator to that, so we remove as many leading ./././'s
### as are present, but some seds (like Ultrix's sed) don't allow you to
### apply * to a \( \) group.  Bleah.

#### Usage messages.

short_usage="Usage: ${progname} CONFIGURATION [-OPTION[=VALUE] ...]

Set compilation and installation parameters for XEmacs, and report.
CONFIGURATION specifies the machine and operating system to build for.

Note that for most of the following options, you can explicitly disable
them using \`--OPTION=no'.  This is especially useful for auto-detected
options.

General options:

--help            Issue this usage message.
--verbose        Display the results of configure tests.

Compiler options:

--compiler        Specify compiler.
--with-gcc        Use GCC to compile XEmacs (auto-detected).
--with-lcc        Use LCC to compile XEmacs.
--with-gcc=no        Don't use GCC to compile XEmacs.
--cflags=FLAGS        Override the default values for CFLAGS.
--site-includes=DIR    Other header file directories.
--site-libraries=DIR    Other library directories.
--site-runtime-libraries=DIR
            Paths to add with -R flag.
--dynamic        Link dynamically if supported by system.
--srcdir=DIR        Look for the XEmacs source files in DIR.
--const-is-losing=no    Allow the use of const in the source code.

Installation options:

--prefix=DIR        Install files below DIR.  Defaults to \`${prefix}'.
--run-in-place          Use the source tree for installation.

Window-system options:

--with-x        Support the X Window System (auto-detected).
--with-x=no        Don't support X.
--x-includes=DIR     Search for X header files in DIR.
--x-libraries=DIR    Search for X libraries in DIR.
--with-ns        Support NeXTstep windows (not yet implemented).
--with-menubars=TYPE    Use TYPE menubars (lucid or motif).
            *WARNING*  The Motif menubar is currently broken.
--with-scrollbars=TYPE    Use TYPE scrollbars (lucid, motif, or athena).
--with-dialogs=TYPE    Use TYPE dialog boxes (motif or athena).
            (Lucid menubars and scrollbars are the default.
             Motif dialog boxes will be used if Motif can be
             found.)
--with-xpm        Compile with support for XPM files (auto-detected).
--dont-have-xmu        For those unfortunates whose vendors don't ship Xmu.

Additional features:

--with-tooltalk        Support the ToolTalk system.
--with-sparcworks    Support the Sun Sparcworks system.
--with-energize        Support the Lucid Energize system.
--with-socks        Compile with support for SOCKS.
--with-xface        Compile with support for X-Face mail header
              conversion (auto-detected).
--with-gif        Compile with support for GIF image conversion
            (not yet implemented).
--with-jpeg        Compile with support for JPEG image conversion
            (not yet implemented).
--with-png        Compile with support for PNG image conversion
            (not yet implemented).
--external-widget    Compile with external widget support.
--with-sound=native    Compile with native sound support (auto-detected).
--with-sound=nas    Compile with network sound support.
--with-sound=both    Compile with native and network sound support.
--native-sound-lib=LIB    Native sound support library.
--with-epoch        Compile with additional Epoch compatibility.
--with-i18n3        Compile with I18N level 3 (not fully supported).
--with-mule        Compile with Mule support.  This doesn't work yet.

Debugging options:

--debug            Compile with support for debugging XEmacs.
            (Causes code-size increase but no loss of speed.)
--error-checking=TYPE[,TYPE]...
            Compile with internal error-checking added.
            Valid types are extents, bufpos, malloc, gc, typecheck.
--error-checking=none    Disable all internal error-checking.
--error-checking=all    Enable all internal error-checking.

Other options:

--puresize=VALUE    Override default amount of space for pure Lisp code.
--rel-alloc        Use the relocating allocator (default for this option
              is system-dependent).

You may also specify any of the \`path' variables found in
Makefile.in, including --bindir, --libdir, --lispdir, --datadir, and
so on.  Note that we recommend against explicitly setting any of these
variables.  See the INSTALL file for a complete list plus the reasons
we advise not changing them.  Specifying a \'path' variable will override
the --run-in-place value.

If successful, ${progname} leaves its status in config.status.  If
unsuccessful after disturbing the status quo, it removes config.status."


#### Option processing.

### Record all the arguments, so we can save them in config.status.
arguments="$@"

### Shell Magic: Quote the quoted arguments in ARGUMENTS.  At a later date,
### in order to get the arguments back in $@, we have to do an
###  `eval set x "$quoted_arguments"; shift'.
quoted_arguments=
for i in "$@"; do
   quoted_arguments="$quoted_arguments '$i'"
done

### Don't use shift -- that destroys the argument list, which autoconf needs
### to produce config.status.  It turns out that "set - ${arguments}" doesn't
### work portably.
### However, it also turns out that many shells cannot expand ${10} at all.
### So using an index variable doesn't work either.  It is possible to use
### some shell magic to make 'set x "$arguments"; shift' work portably.

### You would hope that you could choose an m/*.h file pretty much
### based on the machine portion of the configuration name, and an s-
### file based on the operating system portion.  However, it turns out
### that each m/*.h file is pretty manufacturer-specific - for
### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
### machines.  So we basically have to have a special case for each
### configuration name.
###
### As far as handling version numbers on operating systems is
### concerned, make sure things will fail in a fixable way.  If
### /etc/MACHINES doesn't say anything about version numbers, be
### prepared to handle anything reasonably.  If version numbers
### matter, be sure /etc/MACHINES says something about it.
###
### Eric Raymond says we should accept strings like "sysvr4" to mean
### "System V Release 4"; he writes, "The old convention encouraged
### confusion between `system' and `release' levels'."
